OUT FOR INVALIDS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed April 17,1905. Serial No. 256,048.

Wabash avenue, in the city of Chicago, in the county of Cook and Stateof Illinois, have invented a new and useful Improvement in Cote forInvalids, of which the following is a specification.

My invention relates to that class of cots specially designed for theuse of sick persons.

The object of my invention is to provide a cot that is adjustable to theseveral positions adapted to meet the wants, ease, and convenience ofthe invalid; that can be adjusted so that the invalid is raised from thehorizontal to the sitting position and back to the horizontal; that canbe raised in a straight incline with the head or foot high or low, asdesired; that can be raised at the head and the foot above the center;that can be raised at either end independent of the others that can beraised and lowered in the horizontal position, all changes being madewithout disturbing the occupant; that enables the occupant to' respondto natures requirements without inconvenience, and that can be takenapart and folded together for storage and transportatlon.

The manner in which I accomplish these objects is described in thefollowing specification and illustrated in the accompanying drawings, inwhich- Figure 1 is a side elevation showing the general construction andchanges in position of the several parts of the cot. Fig. 2 is across-sectional view on the line 2 2, Fig. 1, showing the removable partof the mattress and its supporting-frame. Fig. 8 is a top view showingthe construction of the frame and position of the brackets when raisedand folded. Fig. 4 is a detail side view of the mechanism for raisingand lowering the head of the bed. Fig. 5 is a detail view of the top ofFig. 4. Fig. 6 is a plan view of part of the cot looking upwardunderneath the cot. Fig. 7 is a cross-sectional view on the line 7 7,Fig. 1, showing the shaft and mechanism for raising and lowering thebed. Figs. 8 and 9 are detail views showing part of the bracket,barholder, and bar.

In the drawings, A-is the main part of the cot, supported on the legs Aand having suitable cross-bars A to support a mattress. At the head ofthis frame and affixed thereto are two brackets A which arehinged at Aand are thereby adaptedltolbe folded over upon the cot when not in use,as shown by the dotted lines in Figs. 3 and 7. The tops of thesebrackets extend forward over the cot when raised and have a series ofbar-holders A and bars A, the bars being adjustably secured in saidholders, as shown in Figs. 3, 7, S, and 9. These bars are arranged sothe occupant of the cot can reach and grasp one or the other, andthereby change the posit ons of the body while in the recumbentpositlon. Aflixed at the foot of the frame A are two vertical arms Ahaving vertical slots A Above the frame A is a second frame B,

formed of two main parts B and B These parts are joined by hinged jointsB and are provided with suitable cross-bars B The end of the part B issupported by a pair of racks B, which are pivotally attached to theframe B. These racks extend down outslde the frame A and are engaged andsupported. by rollers B and by the gear-wheels The rollers are supportedon suitable S DUCLb GELD- ings in the frame A, and the gears are affixed011 the shaft B which extends through and is supported in the frame A,as shown 1n 1! 1g. 7. Between one of these gear-wheels and the frame Aon the shaft B is a ratchet-wheel B engaged by a pawl B which isplvotally attached to the frame A. On the end of the shaft B is a crankB, by which the gears and racks are operated and the frame B raised andlowered. The ends O of the part B of the frame B are curved down, asshown 1n Fig. 1, and are provided with loose plvotal studs which extendthrough and slide freely in the slots A in the arms A These studs areadjustably secured to the arms A by suitable thumb-screws O.

Affixed to the part B of the frame B are two locking-plates O one oneach side. Each of these plates is adapted to be engaged by a lock-pin Gwhich is adapted to be inserted into suitable holes in the part B of theframe B. When these pins are inserted, the parts B and B are lockedtogether as a solid frame and can then be raised horizontally or raisedat either end to form a straight incline from head to foot or foot tohead, the ends of the frame B when raised at the foot pivoting on theracks B and when raised at the head prvoting on the studs in the ends C.

On each side of the frame B are two hooks O, one on each side of thehinge-joint B. These hooks are adapted to beheld by staples O affixed tothe frame A, and are adapted. to hold the part B or the part B wheneither 'Ioo part is raised at the head or foot above the hinged joint BWhen all hooks are released and the lock-pin C is removed, then bothends of the frame B can be raised abov the hinged joint B Attached tothe under side of the frame A is a small drop-frame D, one end of whichis secured by the hinges D to the frame A and is thereby adapted to belowered at the free end down to the floor. This free end is providedwith a hinged clasp D which is pierced with several holes D and is thusadapted to be engaged by a suitable staple D By this means the frame Dcan be slightly lowered, as shown in Fig. 2, or dropped to the floor.Supported on this frame in the mattress E is a removable part E, asshown in Figs. 2 and 3. By releasing the clasp D and lowering the frameD this part of the mattress can be removed and a suitable vesselinserted in its place for the convenience of the occupant of the cot.Around this aperture the mattress is protected by suitable waterproofmaterial.

The frame B supports a suitable canvas E, which is secured to the sidesand ends of said frame by suitable means. This canvas also has anaperture E corresponding with the aperture in the mattress. On thiscanvas the invalid lies With such bedding as may be required. When thebody of the occupant is lying horizontally and the frame B is notraised, the weight is on the mattress.

Attached to the part B of the frame B are a series of holders F, adaptedto support a series of hoops F, arranged to carry the weight of thebedcloth ng and prevent the bedclothes from touching the invalid.

When my improved cot is constructed as described, and illustrated in theseveral drawings, the frame B may be removed from the frame A and theparts B and B folded together, the racks B being withdrawn fromengagement with the rollers B and gears B and placed along the sides ofthe part B. The brackets A may by the removalof the bars A be folded oneover the other on the frame A and the legs A be closed up under theframe. With the parts so arranged the cot is adapted for storage andtransportation. When in use, the several parts are adjusted asdescribed, and shown in the several drawings. The brackets A are raisedand fixed in position by the bars A". The mattress E is laid on theframe A with the movable part E adjusted over the frame D. The frame Bis then laid on the mattress, the racks B inserted between the rollers Band gears B The ends C are then adjusted in the arms A and secured bythe thumb screw C. The pins 0 are inserted in the part B of the frame Band into engagement with the locking-plates C The hooks C are fastenedto the staples C in the frame A. Suitable bedding is placed on thecanvas E on the frame wheels, a frame, B, formed of tWo B, and the cotis then ready 6f occupancy. The occupant, lying with the head betweenthe brackets A can reach the bars A and use them for slightly changingthe position of the body. The pins C and hooks C can be adjusted atpleasure and the positions of the frame B be changed by operating thecrank B. To raise the foot, that part is lifted and the thumb-screws Cadjusted. To adjust or remove the part E of the mattress E and to insertsuitable vessels in its place, the clasp D is released and the frame Dis lowered and raised and made secure. By the insertion of the pins C inpart B of the frame B and releasing the hooks C the frame B can beraised horizontally or on an incline above the mattress and the mattressbe then removed or supplemented with such padding or additional supportsas the condition of the occupant may require.
